This report uses a newly available dataset – payroll data held by HM Revenue and Customs on over 250,000 working-age people covering April 2014 to March 2019 – to look at monthly and weekly volatility in employee pre-tax earnings. It is one of a very few UK studies to look at high-frequency earnings volatility on a large scale, and the first do so on a sample that is representative of the population of employees in the UK.
